ABSTRACT
Objective:To explore the pharmacokinetics effect of 8 components of processed Baizhu Shaoyao San on rats.Methods:The rats were divided into processing group and unprocessing group, administered with decoction of Baizhu Shaoyao San by gavage respectively. Then, blood was collected from fundus vein at certain time to obtain the plasma. Finally, the contents of 8 components in plasma were detected and compared by UPLC-MS/MS method, and the methodology of the experiment was tested. The drug concentration in blood and the collection time of blood were analyzed by DAS software, and the time curves of different groups were obtained, the pharmacokinetic parameters were calculated.Results:The blood peak concentration, peak time, area under the drug time curve, and average residence time of 8 components in the serum of rats in the raw product group and the fried product group were different to varying degrees.Conclusion:Processed Baizhu Shaoyao San could influence the behavior of the components measured in rats, which may affect the clinical therapeutic effect of Baizhu Shaoyao San.
ABSTRACT
Objective:To explore the effects of different processed products of Epimedii Folium on cytotoxicity and the material basis of toxicity. Methods:By using the SRB method to investigate the effects of different processed products of Epimedii Folium on the proliferation of HaCaT cells; and based on the grey correlation analysis method to establish the data spectrum effect relationship of HPLC fingerprint spectrum-toxicity so as to determine the toxic components and processing methods. Results:The value of cytotoxicity IC 50 of different processed products of Epimedii Folium is as follow: vinegar fried> oil fried > original > single fried > salt fried > wine fried. Among the 12 characteristic chromatographic peaks, Peak No.3 (magnoflorine, correlation value: 0.870) and Peak No.6 (epimedin C, correlation value: 0.851) are highly correlated with the toxicity value. Conclusions:Both vinegar fried and oil fried Epimedii Folium have the effect of reducing toxicity. Magnoflorine and epimedin C may be the main toxic components in Epimedii Folium. The study provides scientific basis for the research on the process optimization of Epimedii Folium concocting to reduce toxicity.
ABSTRACT
Objective@#To investigate the changes of alkaloids in Chinese medicine Phellodendron amurense.@*Methods@#High performance liquid chromatographywas used to detect the content of berberine, corkaline, jatrorrhizine, palmatinebefore and after processing in different processed products of Chinese medicine Phellodendron amurense. The column was Ecosil C18 column (250 mm × 4.6 mm, 2.5 μm), and the mobile phase was acetonitrile: 0.2% phosphoric acid buffer solution (55:45)(0.4 g of sodium lauryl sulfate per 100 ml of 0.2% phosphoric acid aqueous solution), detection wavelength was 265 nm, column temperature was 35 ℃, flow rate was 1.0 ml/min, and injection volume was 3.0 μl.@*Results@#The best processing temperature of brine-dried cork, anthrax, and wine-running cork was below 160 ℃. Themass fraction of total alkaloid was 4.512 7%, 2.789 4% and 4.047 1% at 100 ℃. Among them, the wine-dried cork and salt water-filled cork products and raw products had a high mass indicating that the auxiliary materials for increasing the dissolution rate of alkaloids were salt and wine. Compared with the raw products, the content of berberine and palmatine in salt water-running cork and wine-running cork was obvious. The content of berberine and palmatine in anthrax was significantly decreased, and the content of corkaline and jatrorrhizine did not change significantly.@*Conclusions@#The changes of alkaloids before and after in different processing of Cortex Phellodendron have showed some differences. The different processing and temperature have a direct influence on the changes of its composition, which can changes the chemical properties of Chinese medicine Phellodendron amurense before and after processing.
ABSTRACT
Objective@#The present study aimed to explore the rationality of peeling process of Pruni semen through the determination of amygdalin.@*Methods@#The content of amarogentin in seed coat, seed kernel and total seed of Pruni semen, respectively, were determined by HPLC according to the methods of content determination under Pruni semen in Chinese Pharmacopeia (2015). The chromatographic column was Inertsil ODS-SP C18 (4.6 mm×150 mm, 5 μm). The gradient elution with acetonitrile-water as mobile phase was performed. The flow velocity was 0.6 ml/min, the column temperature was 40 ℃, and the wavelength was 210 nm.@*Results@#The average recovery rate (n=6) was 98.26%. The sample was stable within 24 h, and the RSD (n=6) was 1.12%. The quality of control products was good in the range of 0.02-0.40 μg. The analysis indicated that there is no significant differences (P>0.05) in the contents of amygdalin in seed coat, seed kernel and total seed of Pruni semen.@*Conclusions@#With the content of amygdalin as the index of evaluation, the Pruni semen had better not be peeled.
